CONNECTION BETWEEN VEHICLE POLES AND YOKES.

Specification of Letters Patent.

Application filed December 27, 1919. Serial No. 347,649.

To all wrom it may concern.

Be it known that I, Fonns'r HoorER, of the city of Edmonton, in the Province of Alberta, Canada, have invented certain new and useful Improvements in Connections Between Vehicle Poles and Yokes, of which the following is the specification.

My invention relates to improvements in connections between vehicle poles and yokes, and the object of the invention is to devise a simple and effective connection whereby a yoke can be connected to the tip of the pole and retained thereon when the yoke is in the more or less horizontal position and which will be released when the yoke is turned into the vertical position.

My invention consists of a sleeve adapted to be secured about the yoke intermediately of its length and provided with a hollow boss having a cross slot in the outer face thereof, and a T-shaped member secured to the tip of the pole, all as hereinafter more particularly described, and illustrated in the accompanying drawing, in which Figure 1, represents a perspective view of a connection constructed according to my invention, showing the same applied to the pole and yoke.

Fig. 2, is an enlarged elevation of the tip of the pole, showing the connection in section.

Fig. 8, is an enlarged plan view of the tip of the pole, showing the yoke and connection in section, the former turned in the vertical position and about to be disengaged from the pole.

Like characters of reference indicate corresponding parts in the different views.

1 is the pole and 2 is the yoke provided with the sleeve 3 extending about the same intermediately of its length. f is the hollow boss provided with a cross slot 5 extending through the outer face thereof. 6 is a sultable member having extending portions 7 adapted to be secured to the pole and having a neck 8 at its forward end carrying the cross bar 9, the said member 6 forming with the neck 8 and the cross bar 9 the T-shaped member.

The device is applied as follows :-The

member 6 is attached to the tip of the pole I 1 in such aposition that the cross bar 9 will be vertical. When it is desired to apply the yoke to the pole the yoke is turned in the vertical position and thecross bar 9 inserted into the slot 5 in the outer face of the boss 4:.

The yoke is then turned into the horizontal i position when the cross bar 9 will engage I ing an outer wall spaced from the body of the sleeve and having a cross slot formed therein, and side walls extending between said outer wall and the sleeve, and a coupling member carried by the pole and presenting a shank provided with a cylindrical cross head tapering toward its ends and adapted to be inserted through the slot in said casingto couple the yoke and pole'together.

2. The combination with a vehicle pole and yoke of a sleeve received on the yoke and carrying an integral slotted wall or plate supported in spaced relation to the body of the sleeve and upon one side thereof, to provide an intervening space, and a coupling head adapted to be received in the slot of said sleeve when the yoke is disposed vertically with respect tothe pole and to engage the rear wall of said plate when the yoke is disposed horizontally with respect to the pole, thus coupling the yoke and pole together in the operative position of the former.
